From c3113c393e81feb2193e000794498625fe4a7d5d Mon Sep 17 00:00:00 2001 From: Michal Kazior Date: Sat, 24 Jan 2015 12:14:47 +0200 Subject: [PATCH] ath10k: implement diag event Some firmware revisions may report this event as part of their diagnostics. This avoids `unknown event` warnings and adds tracing for the event.
